Description

Technical Field

[0001] This utility model belongs to the field of video surveillance technology, specifically relating to an underground video surveillance device. Background Technology

[0002] In mining operations, the underground environment is complex and harsh, with problems such as insufficient light, confined space, and the presence of flammable and explosive gases, posing significant challenges to underground video surveillance. Existing video surveillance devices are often vulnerable to damage from the harsh underground environment due to insufficient protective performance, and have limitations in displacement adjustment and rotation angle, making it difficult to meet the needs of comprehensive and multi-angle monitoring, thus affecting the comprehensive and effective monitoring of underground operations.

[0003] The existing technology, with announcement number CN214007137U, describes a 5G-based downhole video monitoring device. This device, through the cooperation of various components including a housing, sliding plate, sleeve, C-shaped rod, and brush plate, achieves multi-directional monitoring and cleaning functions for the camera. However, the device requires high precision in the cooperation of each component, is prone to failure in the harsh downhole environment, the cleaning mechanism is prone to damage to the camera, and its displacement and rotation functions are limited, making it difficult to meet the needs of comprehensive and large-scale monitoring. Utility Model Content

[0004] The technical problem solved by this utility model is to overcome the defects existing in the prior art and provide an underground video monitoring device.

[0005] The technical solution adopted in this utility model is as follows:

[0006] The downhole video monitoring device of this utility model includes a fixing mechanism and a protective mechanism, as well as a displacement mechanism, a rotation mechanism and a camera. The fixing mechanism is located above the protective mechanism, and the displacement mechanism, rotation mechanism and camera are all located inside the protective mechanism.

[0007] The fixing mechanism includes a fixed base, with hanging ears rotatably connected to both sides of the fixed base, a support plate connecting the hanging ears, and a fixed plate fixedly connected to the support plate.

[0008] The protective mechanism includes an outer shell, a semi-circular baffle on the front of the outer shell, a hemispherical shield on the outside of the semi-circular baffle, symmetrical arc-shaped protective plates inside the semi-circular baffle, a first toothed rack on the top and bottom of the inner wall of the arc-shaped protective plate, grooves and through holes on the bottom and top plates of the outer shell, and several heat dissipation holes on the back plate of the outer shell.

[0009] The displacement mechanism includes a slider that cooperates with a groove. The slider has several mounting holes. A second rack is provided on both sides of the slider. The second rack meshes with a first driven wheel. The first driven wheel meshes with a first driving wheel. One end of the first driving wheel is coaxially connected to the second driving wheel, and the other end passes through a through hole and is connected to a first drive motor.

[0010] The rotating mechanism includes symmetrically arranged second drive motors, with a support base between the second drive motors. The rotating end of the second drive motor is connected to a third driving wheel, which meshes with a third driven wheel. The third driven wheel meshes with a drive wheel. The drive wheels are respectively mounted on the top and bottom of the camera via rotating shafts. A synchronous rotating shaft is provided between the third driven wheels. The rotating mechanism is fixed between the mounting holes on the two sliders.

[0011] The camera includes a mounting body and a lens. The lens is located on one side of the mounting body, and the top and bottom of the mounting body are fixedly connected to the drive wheel via a pivot.

[0012] This utility model has the following beneficial effects:

[0013] 1. The fixing mechanism includes a fixed base, hanging ears, support plate and fixing plate, which can easily fix the device to supports of different shapes and positions in the well, and the fixing is firm and reliable. It can effectively prevent the device from loosening and falling off due to vibration and impact in the complex environment of the well, and ensure the continuous and stable operation of the monitoring work.

[0014] 2. The outer shell of the protective mechanism, together with the semi-circular baffle and hemispherical cover, can effectively buffer external impacts and collisions, reducing damage to internal components; the rack on the inner wall of the arc-shaped protective plate works with the displacement mechanism to provide stable guidance for displacement; the heat dissipation holes facilitate the dissipation of internal heat, preventing component failure due to high temperature, thereby comprehensively improving the device's protective capability in harsh underground environments and extending its service life.

[0015] 3. The slider and groove in the displacement mechanism cooperate with each other and are combined with the gear transmission system. Driven by the first drive motor, the camera can be moved smoothly within the protective mechanism. The position of the camera can be quickly adjusted according to actual monitoring needs, thereby expanding the monitoring range and improving the flexibility and adaptability of monitoring.

[0016] 4. The symmetrically arranged second drive motor of the rotating mechanism drives the gear meshing, enabling the camera to rotate flexibly at multiple angles. The synchronous rotating shaft ensures the coordination of the rotation on both sides, realizing all-round rotation monitoring of the camera, avoiding blind spots, and timely capturing the operation situation in all directions underground, providing more comprehensive and accurate video information for safety monitoring.
